All new Dry rock to running tank

[Reef of Fillory]

Hello, I have an issue with my rocks not staying together/shifting. The tank is currently set up and i've tried over and over to get a sturdy base and rockscape.

My question is, can I take dry rock such as BRS reefsaver, build it on the floor, cement it all together and then take my current live rock, put it into my refugium section [all flow goes through the refugium] and put the new aquascaped rocks into the tank?

Would rinsing/soaking in RODI for a few days [or a week] be enough on reefsaver (there isn't supposed to be anything in/on it) to avoid problems with ammonia spikes/nitrate/phosphate?

Is there any issue with moving all of the current bio-filtration [live rock] to the refugium section of my sump? I have fairly high flow coming from my overflows to my sump, but the water goes "over" the baffle from the refugium. Would the rock on the bottom possibly not get enough flow to maintain the bacteria?

Any insight/info would be great!

Also, if anyone's used the reefsaver BRS dry rock, and can comment on any smell/issues you had that would be very helpful as well!

Yes, you can do that - you can also use reef safe expoxy. You can also drill it and put acrylic rods into it.

People have had issues with BRS rock having all kinds of bound terrestrial phosphate - some have not. It is a risk. If yours is full of it, then washing it in acid can help, but nothing takes care of all of it. It can take a year or two in the tank to get it all out.

I wouldn't mind just running GFO after my refugium to help soak up phosphates if they did start to leach out.
